SAW-GAGE ATTACHMENT.

Specification of Letters Patent.

Patented Oct. 26, 1920.

Application filed November 25, 1919. Serial No. 340,509.

To all whom it may concern:

Be it known that I, NILLIs W. GILDE11 sLEEvE, a citizen ofthe, United States, res1ding at Disston, in the county of Lane and State of Oregon, have invented certain new and useful Improvements in Saw-Gage Attachments, of which the following is a specification. w

This invention relates to saw gages, and more particulary to attachments therefor.

The object of the invention is to provide a simple and efficient attachment for saw gages which will show at a glance the exact condition ofthe tooth being swagedthereby avoiding the necessity of the operator stooping over and looking under the gage as is necessary when such attachment is not used. Another object of the invention is to provide an attachment of this character which may be readily applied to any gage already constructed and in use and may be transferred from one gage to another so that one attachment may be employed with any num ber of gages.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit ofthe invention.

In the accompanying drawings Figure 1 represents a side elevation of a portion of a saw with a gage shown applied and equipped with the attachment constituting this invention, said attachment being shown in section,

Fig. 2 is a detail perspective view of the attachment detached, the gage being shown in dotted lines to illustrate the proper position of the attachment relatively thereto, and

Fig. 3 is a transverse vertical section through the attachment.

The attachment 1 constituting this invention is substantially in the form of a split cylinder or saddle 2 composed of block tin or other suitable material with reinforcing bands 2 arranged therearound to adapt the device to have a clip-like engage ment with the opposed edges of the gage G to which it is to be ap lied as is shown clearly in Fig. 2. Eaten ing from the split edges of this cylinder are flaring jaw members or arms 3,'offset from the cylinder as shown at 4, the offset portions 4 bein bent to conform to the flange of the gage (x with which the device is to be connected. These arms 3 are provided at their free ends on their outer faces with sleeve-like members 5 which are preferably formed by bending up the ends of the metal plate from which the device is constructed, although obviously it need not be so formed. Set screws 6 extend transversely through these sleeves and pass through blocks 7 mounted in the sleeves. These blocks 7 have longitudinal bores extending throughout their length and are adapted to receive the shanks 8 of frames 9 which carry reflecting elements 10 and 11, one being in the form of a mirror and the other of a white reflector, preferably of cardboard to form a background for the tooth to be reflected in the mirror.

The frames 9 of these members are preferably constructed of heavy wire or metal rods bent into the desired shape, being here shown rectangular and the shanks S are made integral therewith, being adapted for longitudinal movement in the blocks 7 and also adapted to be turned therein to provide for the adjustment of the frames relatively to the gage in connection with which they are to be used. By so mounting these shanks 8 the mirror 10 and reflector 11 may be tilted at any desired angle and are designed to be positioned one on one side of the saw being swaged, and one on the other.

In the use of this attachment, the cylindrical member 2 is placed on the gage G as shown in Figs. 1 and 2 straddling the gage and with one arm 3 extending on one side thereof and the other on the opposite side, said arms being flared so as to properly position the reflectors which they carry relative to the gage and saw to avoid interference with them. When the device is so placed on the gage the mirror and reflector are arranged at such an angle that all that is necessary to inspect the tooth being swaged is to glance down into the mirror and see exactly the condition of the tooth operated on.

I It is of courseunderstood that it is the drag teeth which have to be swaged down to a fine point and to determine when they have been perfected it was heretofore necessary for the operator to stoop over and look under the gage, but with the device which constitutes this invention applied, he may remain in erect position and simply glance into the mirror to determine the condition of the tooth, the member 11 forming a background to more clearly show up the tooth. Of course, this inspection from an erect position effects a great saving in time as well as relieves strain on the eyes and back of the operator.

The attachment constructed as above described may be applied to any gage already in use, old or new, and adjusted by bending the cylindrical member 2 to adapt the offset flange engaging portions 4 to snugly fitthe flange of the gage in connection with which it is to be used.

In swaging a tooth, the gage Ur is first set on the saw S and then removed to permit the operator to strike the drag tooth T with a hammer once or twice. Then the gage is replaced on the saw and this operation repeated until the tooth is properly swaged, which occurs when the adiusting screw of the gage passes squarely and without touching over the drag, it being important that the swage at the end of the tooth T be exactly beveled to compare with the cutting teeth, and by employing the attachment constituting this invention, the operator can readily see when a perfect sw'age of the tooth has been accomplished.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is 2- 1. A saw gage attachment including a reflector and a cooperating back-ground for the object to be reflected and means for securing said attachment to a gage, the background being arranged on one side of the attachment and the reflector on the other.

2. A device of the class described comprising a saddle for straddling a saw gage having diverging arms on opposite sides with a reflector carried by one arm and a background for the object to be reflected by the other.

A device of the class described comprising a saddle for straddling a saw gage having diverging arms on opposite sides,

one of said arms having a bearing, and a mirror having a shank mounted for lateral and longitudinal adjustment in said hearing,

4:. ii device of the class described comprising a saddle for straddling a saw gage -having diverging arms on opposite sides,

each having a bearing, a shank adjustably mounted in each bearing and projecting in advance of said saddle, and a mirror carried by one shank and a cooperating background by the other.

In testimony whereof I affix my signature in presence of two witnesses.
